Tightness in the calf muscles can be caused by prolonged muscle fatigue or by poor venous return. In this case, the first thing you should do is to take rest and avoid standing and sitting for a long time. At the same time, you can elevate your legs during rest to promote venous return and relieve the symptoms of soreness and tightness. Consider using compression stockings in your daily life to relieve these symptoms. When sleeping at night, place pillows or quilts underneath your calves to cushion them to prevent further aggravation of varicose veins. For tightness in the calves caused by overworked muscles, the first step is to exercise properly, stretching and relaxing afterward. At the same time, warm water can be given to apply hot compresses and massage with both hands can also achieve better results. Every night before going to bed can use hot water to soak feet, while massaging and nudging the corresponding points, knocking the corresponding parts, can also achieve a good relief effect. In addition, the application of Yunnan Baiyao and safflower oil for local activation of blood circulation and elimination of blood stasis can also achieve relief of calf tightness. After sufficient rest and the above treatments, most patients with muscle tightness can achieve good relief.
